description:
Fix skipping of directories that begin with a '.' in -R mode.
It is not enough to avoid displaying the contents of the directory,
we need to set FTS_SKIP to avoid descending into any subdirs too.
Otherwise, if a ".foo" directory has a subdirectory "bar", ls will
descend into bar and display its contents. From Todd Miller
